Abstract	Correction by heating and pressing is used as a method of repair for steel structures damaged by local buckling, but the effect of correction by heating and pressing on mechanical behavior of steel members is not elucidated sufficiently. So to examine the compressive characteristics of box columns corrected by heating and pressing, a series of experiments was carried out. Local buckling was generated in the virgin column by compressive loads and it was corrected by heating below the A1 transformation temperature and then pressing. A compressive experiment for the corrected columns was performed and the results of the experiment were compared with that in the virgin situation. The stiffness in the axial direction of the corrected column decreased and the out-of-plane displacement at the ultimate situation increased compared to those in the virgin situation. This was because of the irregularity of the column’s height due to correction of the panels. In the case that the irregularity was leveled by lathing, they were controlled and kept as those of the virgin columns. In any case the ultimate strength of the box column corrected by heating and pressing was not lower than that in the virgin situation.
